Occasionally we cannot use non-surgical endodontics. At that time, depending on the circumstances, apicoectomy can be effective. This paper is a report of a case observation; the affected tooth, for which non-surgical endodontics could not be use, required apicoectomy. Namely, a post crown, difficult to remove, existed on the 2 tooth, causing a problem with the next tooth, therefore requiring apicoectomy and retrofilling at sealer and guttapercha point. After that, it was crowned with a porcelain veneer crown.
